We used correlation analysis to examine whether changes in grey matter volume in patients correlated with clinical presentation. gray matter volume was markedly reduced in neovascular glaucoma patients than healthy controls in the following brain regions: left cingulum anterior/medial frontal gyrus; left middle frontal gyrus, orbital part; left inferior frontal gyrus, orbital part; superior temporal gyrus/right frontal inferior orbital part. VBM directly suggests that neovascular glaucoma patients have changed in the volume of multiple brain regions. These changes exist in brain areas related to the visual pathway, as well as other brain areas which are not related to vision. The alteration of specific brain areas are closely related to clinical symptoms such as increased intraocular pressure and optic nerve atrophy in neovascular glaucoma patients. In conclusion, neovascular glaucoma may cause paralgesia, anxiety, and depression in patients. [ABSTRACT FROM AUTHOR]
